--- Comment #3 from joseph at codesourcery dot com <joseph at codesourcery dot com> --- Unless someone can identify a commit that deliberately fixed the bug *and added appropriate tests to the testsuite*, I'd strongly advise adding tests to the testsuite before marking FIXED on the basis of those tests now passing (if they are passing incidentally as a result of some other change that didn't add tests directly related to this bug).
